10-4, i saw that and adjusted it but couldn't tell if it did anything. How does the ECU determine a tip-in event? Is there a rate of change for the throttle that is the "trigger" for a tip-in event?

Spent a lot of time adjusting the tune to remove the knock retard from the log. I have these weird "tip in" knock events, this is taken at time stamp 5:46.4, do i just need to pull 5* from this...

Got it! I'll check the logging rate on those, i thought they were set as high as they could go . . . maybe i have too many channels logging at a high rate, how would I know if i'm asking for more...

I've made the suggested changes to the distance tables.

I've pulled timing from the areas that showed knock. Knock is now way down, but i have a few more areas to clean up.

I changed my...

Sirius, thanks for the clarification on the distance tables. I knew some of those were for driving EGR, but hadn't gotten to the point of understanding exactly the impact of the cam timing at each...

Sorry, i should have clarified, I reset SD, TM, and Timing back to stock values, and used your settings for everything else (except the MAF period which i retained and the delay time for the O2...

Ok, I need a sanity check here. And sorry I'm such a Newb and am probably asking really dumb questions at this point.

1) MAF Looks to be pretty close:
144042

Is this an accurate assessment?
...

Just so i'm reading things right, positive knock retard means timing is being pulled due to knock. Negative knock retard means timing is being added because there is lack of knock. Is this correct?...

murfie, thanks for the clarification. I'm going to do some more research on this to better understand Ford's patent and how this all works together, this is an amazingly complex system. Thanks for...

Thanks for the clarification, these were all set to 0 on my stock tune.




First off Sirius, i wanted to thank you as I am using the tune you provided some time ago on another post for my...

Engineermike, thanks for the response. I'm pretty sure I need to re-read this about 100 more times before I can digest everything! Thanks for all this information.

Also, I am still very much...

The distance tables are all stock including Optimal Stability.

I noticed this when i changed my shift strategy to hold gears a little longer and not bog down in town. In increased RPM has...

Thanks for taking the time to review my log and tune file!

Those tables, in my tune, are stock (other than fixing an error in the OE table at a MP that i don't use . . . not even sure it was...

I have been working through the SD tables and Torque Models, and while they aren't perfect, they are getting better. But, i've had this issue show up, while driving, when i release the trottle, i...

Hopefully some will find this useful, I couldn't find anything like this on the forum.

I've historically tuned in SCT ProRace, not great these days, but the trans tuning portion was nice because i...

Thanks so much to R8Bill and murfie for posting this, it has been very helpful in figuring out how to adjust my torque modeling. I wish there was a way to give thumbs up or at least @ them in a post...

Awesome, thanks so much! I'm actually reading up on calibrating the MAF right now. All the fun begins tonight lol.

The raptors don't have the IMRC's, and i think they only use a few of the map points in contrast to the coyote . . . i believe that is because we have a single overhead cam so both exhaust and intake...

Yes, i do have a stock file.

Can you help me understand what looks off with the Distance Tables? Only asking because I want to learn, not because i'm questioning your comment.

Awesome, thanks so much for the help!

I will take some measurements on the MAF size and swap the stock one back to see if it makes a diff (this one replaces teh overflow/degas bottle, so i won't...

Oh, and injectors are stock. When i first saw the deviation in trim bank 1 vs bank 2 I swapped to another set of stock injectors i had to see if it would go away, but it made zero difference.

Here is also a run yesterday in the rain, i was testing out the new full time 4 wheel drive transfer case, but i had a run from low speed at near full throttle. It has a lot of knock retard going on...

Sorry, I didn't think the tune file would be valuable, its not actually my tune but one that was purchased. I'm planning to start my own tune from my stock file, but i need to know a couple things:...

Long story, i'll make it short. I just bought this truck 4 months ago, I installed a new to me motor that turned out to be built and running 11:1 compression. The truck has 172k miles on it, and a...
